The perennial trading card game from Wizards of the Coast made its Android debut last year, and it seems that the developers intend to give it regular updates, just like the PC version. Magic 2015 includes an expanded collection of cards that match the physical card game, though you'll have to shell out quite a lot of cash for the full set - not unlike the real-world counterpart. Magic 2015 is a free download, but you'll need at least 1.2GB of free space to hold it.

Developer CD Projekt Red has something impressive in the works for fans of The Witcher in need of a mobile fix. Its upcoming game, The Witcher Battle Arena, is a multiplayer experience akin to DotA and League of Legends, but set in the rich medieval universe made popular by the PC/console video game series that's been around since 2007 (themselves based on a series of books). The game was demoed at this year's E3, and it looks awesome.

In the future, sports won't look the way they do now. They will be faster, more complex, and completely saturated with bright neon lights. No game will be immune, no matter how small or seemingly innocent, including dodgeball. Jolt offers a taste of what a futuristic version of this game will look like, and it gives two players the chance to experience it on one device.

According to Wikipedia, there were 19 entries in the perennial Worms franchise before the latest game was published on iOS last year, not counting re-releases, ports, spin-offs, and expansion packs. So why is this one simply titled Worms 3, when in fact we've already had Worms 2, Worms 4: Mayhem, Worms 2: Armageddon (published after Worms 4, by the way), and Worms: Ultimate Mayhem? Who knows. Apparently fans of this series aren't bothered by inconsistent numbering schemes.

As a game centered around using a smartphone to get ahead on the streets of Chicago, it's only natural that Watch Dogs would get a companion app. But this isn't your typical bonus offering that just provides a mini-map, some background information, and a few doodads. Watch_Dogs Companion: ctOS is a multiplayer extension to the main game. While console or PC players are doing everything they can to make it from checkpoint to checkpoint, mobile gamers are giving their all to stop them.

Listen, EA, you're one of the biggest video game publishers in the world. It's not my place to tell you what to do, and far be it from me to say that you have to support Android's standard online and social gaming featureset in your games. But it would probably be a good idea. Case in point: the over-the-top basketball game NBA Jam. The title just got updated with Google Play Games support.

When Namco's Tank! Tank! Tank! served as Wii U launch game in November of 2012, it was criticized for having little more content than a mobile game. As it turns out, that wasn't an exaggeration. That game's one drawing feature, hot multiplayer tank-on-tank action, is now available For Android in much the same form thanks to Iron Force from Chillingo and Cool Fish Games.

Iron Force lacks a single-player campaign, outside of the ability to play against bots.

There are definitely a few features lacking in the way paid content is handled in Google Play – gift codes and free-to-paid app transition, for starters. According Google's GDC announcement, the company isn't addressing those issues in particular, but some other features are coming to Google Play in the form of some new developer options and support for in-game gifts.

Microsoft has already dabbled around with expanding the Xbox Live experience to mobile devices, but if a recent report from The Verge is to be believed, the company may be about to ramp up its efforts significantly. Our good friend Sources, who is familiar with Microsoft's plans, claims that Microsoft is building a platform that would extend Xbox Live functionality to Android and iOS. Instead of using Google Play Games or Apple's Game Center to track achievements, find other players, and compete with one another, you would be able to use Xbox Live instead.
